air flow meter

[sergifed91]

I recently ran my airline from my skimmer to the outside. my pump only has the lph for water flow. is there a good a descent air flow meter that I can use to measure airflow through my tubing to get some idea on what it's pulling?

Dwyer were the go to when everyone thought more air was better. I have one in a box somewhere. While it's nice to know, you'll get bored quickly and wonder why you spent $50 on it.
